how to Lie effectively???

be prepared,think about any questions they may ask you and have an answer for them,dont say umm and dont add too much detail and remember what lie you have told to what person,my sister is always forgetting who she has told what and thats how she gets caught out so often. Apparently though spies are told that they are not to lie if they get caught,they are to say as little as possible,so i suppose that might work too!

Look straight on the eyes of the person. Never look left 'cause it's a sign that you're not telling the truth because it's the side of your creativity. When you look at the right side, it means that you're thinking of a logical answer - that maybe either be a lie or the truth. To be on the safe side, just look straight on your companions eyes when you tell a lie. :)
